So if I do manage to get my LAN completely IGMPv3 capable and thus allow 
the use of SSM, all it takes is one person
plugging in a machine running IGMPv2 and SSM breaks.  This probably means 
that SSM is unimplementable except
in some special cases (example: one host per vlan).

I see similar lack of concern about real world security in wireless routing 
protocols (and DHCP and IPv6 and PIM and ...).

Thanks for the info.
